Question

Find the arc length for arcs of circles as follows:

Answer 1

Answer:

≈ 11.78 in

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × $\frac{\frac{\pi }{4} }{2\pi }$ ( cancel 2π on numerator/ denominator )

     = 15 × $\frac{\pi }{4}$

     = $\frac{15\pi }{4}$

     ≈ 11.78 in ( to 2 dec. places )
